The principal object of the presentmven- ,tion-is to provide asimple'and eflicient device Which will quickly and easily out suchtenacious material into pieces or sizes suitable to be receivedwithinthe melting kettle. Other objects are to reduce the cost, s'izeandweight operatej The invention consistsin the cutting device andin theconstruction, combinations and arrangements of parts hereinafterdescribed and claimed;

In the accompanying drawing, which forms part of this specification andwherein 7 like symbols refer they occur, i e 7.

Fig.1 is a side elevation of a cutting device embodying my invention,thedevice being shown positioned on a barrel andreadyfor to like partswherever use in cutting through the material packed therein;

Fig; 2 is an end elevation of the parts shown in Fig. 1.;

ticularly for use in cutting bituminousmate-3 rials, such as asphalt,pitch or tar; that are packed in containers in the form of woodenbarrels or metal drums. As shown in the accomnanvin drawin a nortablewindin de- .toosoft' and tenacious to permit the material to be split orbroken into pieces small enoughof such devices and tomake them easy to,v

Thecutting device isused as follows z when the temperature is such that.the tar, asphalt; or pitch cannot be broken into pieces of the desiredsize, the blockof materialisfirst removed from the container, if theinner .surface thereof has been properly chalked to pre- The block isthen laid on its side, and the winding device or winch is placed on topof the block with its winding drum extending longitudinally thereof andwith the concave bottoms of theend standards fittin the cnnvmz snr drumwith the end fitting on oneend of the cable disposed on one side of saidlug and with the end fitting on the other end of this cable disposed onthe other side of said lug. The winding drum is then rotated by means ofthe crank handles, thereby causing both ends of the cable to be woundupon the drum and the loop tobecome smaller and smaller and thus cutthrough the block. The winding device or winch is then shiftedlongitudinally of the block and adjusted "and operatedtoc'ut the sameinto pieces of the desired size.

In the event that the tenacity of the-material is such that the blockcannot be removed from the containenthe wallof the container-is cutthroughby means of an axe Qr-othersuitable'instrument; and the Winch orwinding device is placed. on the barrel with the cable entered withinthe cut and-engaged with the block, afterwhichthewinding device or.winch is operated in the manner above described to draw the cuttingwire through the block. 7 r

- The hereinbefore described cutting device has numerous advantages. Itis simple and easy to operate, there are few partslto break orgetout-o'f repair, and it is capable of being easily carried in the handor transported from place to place.-

What I claimis:

1.A cutting device for block'materials of the kind described comprisingawinch adapted "to be -mounted on the block of'materi-al and a cuttingcable adapted to be looped around said block of material with'both endsattac'hedto said winch to be wound thereon, whereby the action ofwinding said cableon said winch causes the cable to be drawn throughsaid block of material. 1 2. A cutting device of the kind describedcomprising a winch including a winding drum and means forv rotating saidwinding drum, and a cutting cable, said winding drum being provided witha radially projecting lug having notch therein which extends longi-'tudinal-ly of said drum and is adapted to receive both endsof saidcable, said ends of said calble being provided with end fittings of awidth greater than the widthof said notch.
